Time's Up: 660kW R33 GT-R animal

Although your first glance may lead you to believe that this BCNR33 is nothing more than a stock example, once you’ve been lined up next to it, you’ll know that your time’s up

For an unknown reason, people still harbour an unwarranted amount of animosity towards perhaps one of the most underrated GT-Rs of the model’s linage — it may be a result of its curvier body shape and heavier stature, but is that really a reason to hate a car that much? We think not, and surely no one is under the illusion that, even in stock form, an R33 GT-R would be slow. But those fool hardy enough to face off with this R33 will likely be shat on in the most glorious of fashions. Why? Because there’s an R34 N1 block-based HKS RB28DETT hiding inside this unassuming piece of tin — and that’s just the tip of the iceberg.

Self-described RB fanatic Kris Rana picked up his Series 3 R33 GT-R just over 18 months ago. He puts the purchase down to fond childhood memories: “I got into cars because of a family friend. He owned an RB25DET when my brother and I were around eight or nine years old, and every time we went over to his to visit he would take us for a spirited drive. Ever since then I’ve been in love with Skylines and RB engines.”

Kris didn’t want to feel like he was sitting in a 660kW car when inside, so the interior is pretty much as OEM as they come, with all that power just one depression of the go-pedal away

 

 

Kris went on to own everything from Subarus, GTI-Rs, and Toyotas, to M-series BMWs and a raft of Skylines. But he was unsatisfied. “None of them seemed to cut the mustard, and I always wanted to get my hands on a GT-R.”

He stumbled across what he thought would make the perfect street weapon down in the windy city of Welly. It was already fitted with a N1 bottom-end housing, a HKS 2.8-litre Step 3 full counterweight billet crankshaft, along with the accompanying rods and pistons, and had a full service and build history, having been built by Jon Peplow at Spec Performance in Christchurch. The build history later revealed that it had been imported into New Zealand as a single-owner car and originally purchased by a technician at the Nismo Performance Center in Tokyo, Japan.

The head had had a session of CNC-porting at Kelford Cams to the company’s drag head specifications, and been fitted with Kelford’s 292-degree, 11.5mm lift drag cams. A combination of Kelford 1mm oversized race valves, springs, and titanium retainers was also chucked in for good measure. The aim was for it to be able to withstand serious amounts of boost — with the engine running on 32psi, that was a pretty wise call. 

The bottom end was built to replicate that found in the legendary seven-second HKS R33 GT-R drag car, and comprises a R34 N1 block with HKS 2.8-litre Step 3 full counterweight billet crankshaft, rods, and pistons

Once it had made the trip back up to Auckland with Kris, he took it to Brendon at BNR Engineering — chosen for such a task due to the time and attention that he puts into doing things right the first time — for a full teardown check. Thankfully, everything was there as described — and when you’re talking about parts like these, that’s pretty damn important. The pair quickly set about making further tweaks to draw power out of the bulletproof bottom end. 

With a handful of other high-end Japanese and Australian components fitted — too many to list here — the car was sent over to Grady and Dan at Hitech Motorsport for tuning. While they seldom work on street cars — they spent roughly a month dialling it in to the nth degree through the Link G4+ ECU.

The end result was a whopping 660kW on 32psi running E85, and 498kW running 98 octane through the flex-fuel sensor — it’s even set up for two-step launch control with anti-lag. Words can’t describe the aural symphony that it produces.

Kris told us that the only thing holding it back from pumping out even higher figures are the two GReddy TD06-20G turbos that have already undergone the Turbo Care treatment, having their housings machined to accept billet internals. “If you wanted to chase more power, all the supporting work is there to slap a big single on and really crank. But my intention has always been for it to be a weapon of a street car, and any more would be crazy — it’s already a bit loose for a street car, really,” says Kris. 

It wasn’t just the engine that received a rework. The factory five-speed was rebuilt with strengthened internals and fitted with a Nismo Competition twin-plate clutch and lightened flywheel combo. Nismo 1.5-way limited-slip differentials (LSDs) can also be found at the front and rear of the drivetrain. 

When it came to the interior styling, Kris was adamant that he would maintain as much of a stock look as possible. “The interior is completely standard, so you get into it and it feels like a stock car. It’s comfortable, air conditioned, and feels like what a stock car should.” He continues, “You can drive it out on the street and forget what you’re behind the wheel of, until you put your foot down, and then it feels like something else.”

“There’s something about the big chunky look of the R33 that just made it look tough,” says Kris, “and I was fortunate to find the last of the Series 3 R33 GT-Rs … which was the best of the lot, in my opinion”

 

 

That same ethos was carried out to the exterior styling, with nothing more than a GReddy GRacer front lip and set of 18x10-inch BBS LMs wearing Nexen semi-slick rubber added to the factory bodywork. Kris commissioned a fresh lick of jet black courtesy of Jiten at Advanced Autobody and Spray. While the BCNR33 remains fairly uncommon in any colour here, you see even fewer in black, according to Kris. And while it appears to sit on factory shocks, hidden behind those BBSs is a set of HKS Hipermax drag coilovers just waiting for the two-step launch to hit them.

The proof really is in the pudding with this one. Those who dare to go up against it would only make that fatal mistake once, and when it comes to daily-driving duties, the GT-R takes it all in its stride. Kris has clocked up 6000km in the last two months alone. If we owned it, we probably wouldn’t want to get out of the seat at night either. Why R33s still cop so much shit within the Skyline family is beyond Kris — and us, for that matter. If there was ever one shining example of exactly why they hold their own, this is it.
